SLASHER.

SPECIFICATION forming part of Letters Patent No. 372,692, dated November 8, 1887.

Serial No. 235,952. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES MCCA'RTY, of Fall River, in the county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in Slashers, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the. accompanying drawings, forming part of this specification, in which- Figure l is a side elevation of a slasher'embodying my improvement, some of the parts not necessary to exemplify the invention being omitted; and Fig. 2, a top plan view of the same, certain parts being represented as broken away and others shown in section.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

In slashers as ordinarily constructed the yarn-cylinders are liable to be turned irregularly, causing the yarn or threads to break or snarl and thus produce poor work. To obviate this difficulty or objection I make use of a friction or tension device, by means of which the movement of the cylinder may be perfectly governed, any desired degree of tension or friction being applied in accordance with the nature of the work or the circumstances of the case.

I have represented each of the cylinders shown in the drawings as provided with a tension device; but as the mechanism of each device is substantially the same, I will describe that for the large or main cylinder only.

In the drawings, A represents the frame of the machine; B, the large or main cylinder; C, the small cylinder, and D the shaft.

The shalt Dis journaled horizontally on the frame-work of the machine and provided with a miter-gear, E, which inter-meshes with a miter-gear, m, journaled to revolve on a stubshaft, x, which projects from the standard 1; on the frame of the machine. A sprocketwheel, H, is journaled 011 the shaft 00 with the miter-gear m, being attached to said gear in such a manner as to revolve therewith.

Journaled to revolve on a stub shaft, f, projecting horizontally from the frame of the machine above the-shaft or, there is a dish-shaped disk, J, and friction or tension disk K, sa d tension-disk being adapted to work in frlctional contact with the outer face of the disk J.

Secured to the outer face of the tension-disk K there is a sprocket-wheel, L, a corresponding sprocket-wheel, M, being secured to the inner face of the dish-shaped disk J and journaled to revolve with said disk on the shaft f. A sprocket-wheel, N, is secured to the shaft 1 of the main cylinder B, said wheel being connected with the sprocket-wheel M on the shaft fby an endless chainbelt, z. The sprocketwheel H on the shaft 00 and sprocket-wheel L on the shaft f are also connected by an endless chain belt, t. The outer end of the shaftfis threaded and provided with a tension-nut, 1", adapted to force the disk K against the disk J.

In the use of my improvement the disks J K are brought into frictional contact by the nut a, the movement of the cylinder being readily regulated by the tension device in a manner which will be obvious without a more explicit description.

The tension device for the cylinder 0 may be omitted, if desired.

I do not confine myself to constructing the friction or tension device precisely as described, or to locating it in the position shown.

Having thus explained my invention, what I claim is- 1. The combination of a cylinder having a sprocket-wheel on its shaft, a stub-shaft having a screw-threaded outer end, a sprocket wheel loosely mounted thereon, a chain connecting said sprocket-wheels, and two friction-disks loosely mounted adjacent to each other on said stub-shaft, one of which is rigidly connected with said sprocket-wheel and the other of which receives positive rotary motion from a suitable source of power, and a nut on said screw-threaded portion of said stubshaft for adjusting the friction between said disks.

2. The shaft D, carrying miter-gear E, the stub-shaft 00, carrying miter-gear 'm, meshing with miter-gear E, the sprocket-wheel l-l,also carried by said stub-shaft, the stub-shaft f, having ascrew-threaded outer end, the rigidlyconnected sprocket-Wheel Land friction-disk N, in combination with the nut a" on said K and the rigidly-connected sprocket-Wheel screw-threaded outer end of said stub-shaftf M and friction-disk J, all mounted on said for adjusting the friction between said disks. :0 stub-shaft f, the faces of said friction-disks 5 being in contact, the cylinder B, carrying Witnesses:

sprocket-wheel N on its shaft, and the chain SAML. D. LAWTON, belts connecting Wheels H and L and M and P. I. MORRIS.
